QPECIFICATION forming part of Letters Patent 0. 720,247, dated February 10, 1903.

' Application filed May 31,1901. Serial no. 62,584. on model.)

To all ZUhOTIb it may concern.-

Be it known that I, TOM HANSON, a citizen of the United States, residing at Denmark, in thecounty of Vermilion and State of Illinois, have invented certain new and useful Improvements in Cultivators, of which the fol-' lowing is a full, clear, and exactdescription,

' reference being had to the accompanying drawings, forming part of this specification.

to My invention relates to an implement for treating the soil between rows of plants, and has for its objects to provide an effective implement for accomplishing the purpose stated.

- In carrying out my invention 1' provide the implement with two sets of soil-treating parts adapted for use either together, in which use one set (pulverizers) pulverize the ground stirred up by the other (stirrers) and regulate v the penetration of said stirrers, or for use separately, for which purpose the implement is convertible by having some ofits parts in! terch'angea'ble, Wherebv'the soil may be treated in different specific ways.

a My implement is preferably adapted in its structure to have mounted thereon certain novel insect-exterminating mechanism, described and claimed in my application filed June 23, 1898, for which Letters Patent No. 681,739 were issued November '13, 1900.

My present improvements are embodied in an implement consisting of a longitudinal frame, a front supporting-wheel, a rear support in the form of wheels or pulverizingdisks, draft appliances, controlling-handles,- 55 5 a specially-constructed four-sided base-frame supported from the longitudinal frame when the wheels are to control the depth of penetration, but adapted for use alone and to receive the controlling-handles when wheels to limiting penetrationof' soil-stirring parts are not desired, said base-frame being expansible through meansof the handles and constructed with special reference thereto, improved soilstirring parts adapted to the base-frame,"and certain other novel features of construction, all of which will be hereinafter fully described,and particularlypointed out in the claims. 3 v v In the accompanying drawings, forming part of this specification, Figures 1 and 2 are 'the base frame. views of parts by which the controlling-han- 75 respectively a side elevation and a plan of my improvements all embodied in a single implement and including the base-frame and soil-stirring parts carried thereby and the longitudinal frame from which the base-frame is suspended, with the front traction-wheeland rear pulverizing-disks upon which it travels and the draft connections throughv which itis drawn.- Figs. 1 and 2 are respectively a side elevation and a plan of the base-frame, with its associated parts, in form for use as a cultivatorwithout vthe longitudinal frame and its accessories. Figs. 1 and 2 are respectivelya side elevation and a plan of the longitudinal frame and its accessories without the. base-frame and soilstirring parts, but in form for use as a pulverizer. Fig. 3 is a rear'view of parts shown in Figs. 1 and. 2*.

.Figs. 4, 5, and 6 are detail views of the controlling-handlesland their adjusting crankrod which screws. in or out in sockets formed upon them, thereby determining the space between the handles and fixing the width of Figs. 7 and8 are detail dies are connected to the rear standard on the longitudinal frame. when the baseframe is not used. Fig. 9 is a'detail view of the rearjoint of. the side bars of the main frame andthe ful crumn thereon for the controlling handles. Fig. 10 is aplan of thecen tral cross-rod connection of the main-frame diagonal braces. Fig. 11 is a sectional detail view illustrating the connection between the inner ends of the handies and the diagonal tie rod or brace through and 1d are detail views of the rear pulverizing and supporting disks and their mounting, by

which the soil turned up by the stirring de- 9o vices of the base-frame is broken up and the penetration of said stirring devices limited ,f

the mounting of the disks being adjustable vertically bya rearward-swinging movement to regulate their height relatively to the soilstirring devices,and thus determine the depth of the letters. penetration. Figs. 15,116} and 17 show by side, end, and plan views the'form' of the soil-stirring devices mounted on the base-frame. Fig. l8shows bybottonnplaii ms sion 30 of the cutter 17 for assisting in sup-- porting the latter, and this extension,together- 18, is below and slightly off center in the direction of movement of the said cutter with regard to the pivot on the cutter 17, thereby permitting the cutter 18 to start easily in moving from a state of rest. The range of movement of the cutter 18 is such that when it has reached the limit of its movement the line of the pivots on the cutters will be at a right angle to the length of the stock, and any tendency of either cutter to be forced back into the stock is resisted by the other cutter, as will be seen by reference to Fig. 2, where the tool is shown with the cutters expanded. Each of the cutters is provided'with an upper extension having a square shoulder 28, adapted when the cutters are expanded to bear against the upper wall of the slot in which it moves, and the ends of the said ex-' tensions are flattened and engage the flat under face of the bar 23, which serves as an abutment therefor. This arrangement insures distribution of the impact, as longitudinal pressure is resisted by the stock forming the upper walls of the apertures 15 and 16 and the pin 23 and lateral pressure of each cutter is resisted through the medium of the link by the other. The abutment-bar 23 alone may be relied on to receive the impact of the blows struck by the cutters; but preferably I make the tool as shown, the cutters having the shoulder 28, designed to engage the upper walls of the 'slots 17 18. The vertical movement of the cutter 18 is of course limited by the bar 23 and the upper wall of the slot 16.

If desired, the stock may be provided with a shelf or ledge 29, wherco'n rests an extenwith an extension 31 at the bottom of the cutfor 18, is designed to close the apertures at the bottom thereof when the tool is operating to reduce to a minimum the ingress of dirt and mud or slushinto the chamber of the stock and obviate interference with the free movement of the cutters and also to engage the wall of the stock to limit the outward movement of the cutters.

In operating with atool having butone cutter the stock opposite the cutter is thrown against the side of the shaft or bore and soon becomes ground away. With a double cutter, as shown, the stock is centered in the shaft and held away from .its walls, avoiding this objection and lengthening the life of the tool.

In use when the tool passes out of the lower end of the well-casing the spring 22, which is in a compressed state while the tool is passing through the casing, is permitted to expand and in doing so it elevates the yoke, carrying with it the cutter 18. As the blade 18 moves upwardly it is thrust out by the link 19 and reacting'on the cutter 17 forcesthe latter through the slot 15. When the tool is drawn into the well-casing for removal, the front edges of the cutters, which may be bev- The drill heretofore described is of that:

character in which water is introduced through the chamber of the drill-stock into the bore in order to free it of the boring-meal. With the ordinary tapping-drill the bar 23 may be dispensed with and no passage for the admission of water being used a block employed in lieu thereof to receive the impact of the blows struck by the cutters and also to support the expanding-spring.

The modified construction is illustrated in Fig. 5, where 33 indicates the drill-stock provided with a threaded boss to receive a cap, (not shown,) to which is adapted to be attached the lifting rope or cable. Secured to the top of the stock by a bolt 3; is a block 35 of the same thickness as the cutters, which latter are similar to those seen in Figs. 1 and 2, and the lower face of this block forms an abutment, against which the upper ends of the cutters bear when expanded in like manner as they engage the bar 23 in Fig. 2. The block 35 is provided with alongitudinal aperture 36, wherein is located an expansionspring 37, coiled about the central securingbolt 34. The cross-head 38 of the connectingrod or yoke 39 has an aperture through which the bolt 34 passes, and the spring 37 reacts between the lower end of the block 34 and this cross-head to elevate the yoke. The construction in all other respects is similar to.

that heretofore described.

I claim as my invention- 1.
